The One Direction star - who called it quits with his long-term girlfriend Eleanor Calder last month - was seen leaving the Cirque le Soir nightclub in Soho, London at four in the morning alongside the mystery girl.

A source told the Daily Mirror newspaper: "It was a really wild night. Louis had his own booth and was getting complimentary drinks all evening.

"Louis had his own security guard there to make sure he could really let his hair down."

"He's really in the mood to party at the moment, to make the most of his single life."

Louis and the unknown blonde travelled back to his North London home together whilst his pals were said to have ordered a second taxi for a group of women, who joined them for an after party at Louis' house.

The party ended at 7:00, with some of the 23-year-old singer's pals enjoying a game of football in his garden until the early hours.

It is not the first time since splitting from the 22-year-old student that Louis has been seen with another woman.

Whilst the band were in Thailand, Louis was spotted smooching with a mystery girl, later identified as Lucy Julian, the daughter of multi-millionaire fashion designer Alexander Julian.
